used aquarium

Hi all, Me and my family just got settled into our new home in the Nashville, TN area. I’ve been out of the hobby for a little while, but I finally have a designated wall in the house for a large tank I’ve always dreamed of! As we are unpacking and putting things away, the time for me to start...

Redsea reefer 170 with screen lid, DC pump, Klir-4 roller filter, Coral box skimmer, jebao gyres. Cleaning up my fish room, will be listing other items shortly. Pick up only from downtown Sarasota, Florida area.

This tank is for sale near me. I had questions about the model but they didn’t have an answer. It’s a redsea 425 xl with extras. I talked them down in price to 800. No powerheads but nice lights as well https://offerup.co/ybrf7ya2XWb

Hi Everyone, I’ve been wanting a larger tank for some time now. However, in the past year and a half, I’ve had some major life changes. I moved out of a rental and into my first actual home, got married, and we are now expecting our first baby! Before all of that took place, I did have a...

Im leaving the hobby for a bit (planning on moving and buying my dream car so it's not too sad) and I need to get rid of all my gear for the time being to be able to do so. these are great deals for anyone trying to start a large sps tank! Tank & Filtration: Red Sea Reefer 750 XXL w/ custom...

I recently purchased a used innovative marine 20 gal nuvo AIO how would I best and safely go about cleaning it without the silicone being damaged? I’ve seen mixed takes. Water stains aren’t horrible but there is lots of build up in the sump. Ty in advance!

Picked up a 125 gallon tank decently priced with stand. Tank was up and running when I picked it up had to drain and rehome the fresh water fish that were in it. My concern is previous owner resealed the tank or so it looks. Top frame has cracks in the corners and the glass on the one side...

First time poster, longtime reader of reef2reef! I currently have a 29 gallon FOWLR tank that I've had for two years; I've had a lot of success with it. I love this hobby, and I'm now ready to get a large reef tank, probably in the 125-170 gallon range (i.e., just big enough to house a tang or...

1st post here, sorry if any of this is re-post but I just want to be sure I'm doing things right. I bought a 180ish gallon used from a local store, it’s been dry stored in a garage tell I was able to get to setting up. Well life happened and it got moved 3 times and one of the top braces got...

Any used tank advice needed. Might get a running WB 90.3 that’s 5 years old. Would anyone hesitate due to older seals? Pictures look clean, has some upgrades, reefmat, return pump, decent skimmer. I don’t want to spring a leak in two years so is it worth just starting new?

Hello everyone from South Florida. I am not new to this site, it’s a great resource that I have used frequently to answer my questions about reefing. But, I don’t post much because almost all questions I had were already answered here. But I’ve been reefing for little over a year. I started...

I recently bought a running system from someone trying to get out the hobby. It was running at their home when I picked it up. The livestock included 2 damsels, a small torch, 2 small duncan colonies, and a toadstool leather. It took about 5 hours to get it broken down, transported to my house...

So let me get this started by introducing myself. My username is homage to my 2 crazy kids 4 and 8, they sure do always keep me on my feet. I am a long time freshwater keeper, my last tank being a 90g planted with C02. I have some close friends in the hobby who finally pushed me to take the...

I came across a used RedSea Reefer XXL 625 for a great price and I remember hearing that there were some issues with the older RedSea models stand and support system. Would anyone know if the 625 fell under that category and if that is something I should worry about when looking to purchase the...

I’ve already got a build thread on here but I’m making a new one since this is a new tank! It’s a BioCube 16 LED and I got it completely dry, with nothing but the tank, pump, and a couple unopened filter cartridges. I did not know it was a used tank, but it is, and I found out after the fact -...

Hi Everyone, I have had saltwater aquariums for the past 15 years and kept everything from seahorses (in a FOWLR setup) to reef-keeping. I currently have a 46 gallon bowfront reef tank that has been running for the past 8 years. I recently purchased a 180 gallon bowfront (74x24x24) that I will...

Hi, I just purchased a used 180 gallon bowfront aquarium that is going to need to work before I can get it up and running. It currently is drilled for a single overflow in the right corner but I am considering adding an additional overflow in the left corner for better water filtration down to...

Howdy! As stated in the title, proud owner of a new Max Nano. Filled it with freshwater to check all of the systems. Pumps appear to be working fine so will drain and buy some RO/DI saltwater from the LFS and some live sand and rock to get started! A couple questions though: 1) What is the...

Hello everyone Today I will pick up a used Red Sea Max Nano from a guy in my community. He just moved all fish and corals into his second (and bigger) tank. Now as the tank was running until yesterday it will come pretty "dirty". Now I wanted to ask you guys, how would you properly clean the...

I'm new to the hobby and picked up this 125g used tank a few days ago. The gentleman I bought it from still had water in it until the morning I went and picked it up. Now that I have been able to look it over, I've noticed areas in the seams where he must have hit the silicone with the algae...

Hey there! I'm new here, but not new to the hobby. I've had freshwater and saltwater tanks, on and off for about 30 years. My 16-year-old son recently expressed an interest in getting a saltwater tank (we currently have freshwater), so I jumped at the chance to get back in and do this together...
